• B. (i) and (iii)
• C. (ii) and (iv)
• D. (ii) and (iii)

Answer 1

The correct option is D (ii) and (iii)

The property of metals to be beaten into thin sheets is called malleability. Using this property, cooking vessels are made.
Metals are good conductors of heat, which is an essential property for making cooking vessels.
Aluminium is very malleable in nature and it is a good conductor of heat, which makes it an excellent choice for making cooking vessels.
Aluminium is also lustrous in nature and a good conductor of electricity but these properties are not essential for making cooking vessels.
